A/C Expansion Valves

Expansion valves are essential components of the air conditioning system that regulate the flow of the refrigerant, enabling its effective expansion and cooling of the air in the vehicle's cabin. The precise operation of these valves ensures the efficient operation of the entire air conditioning system and the thermal comfort of passengers. In the Global Parts automotive store you will find a wide selection of used car parts , including expansion valves , perfectly matched to brands such as BMW , Audi , Mercedes , Volkswagen , Mini and others .

What functions do expansion valves perform?

Expansion valves play a key role in the air conditioning system:

• Refrigerant Flow Control – Regulates the amount of refrigerant supplied to the evaporator based on system load.
• Reducing refrigerant pressure – They expand the refrigerant, allowing it to be effectively cooled in the evaporator.
• Improving air conditioning efficiency – Thanks to precise flow regulation, valves ensure optimal operation of the entire system.
• System component protection – Enables the system to operate smoothly, reducing the risk of overloading and damage to other components.

Why is it worth taking care of expansion valves ?

A malfunctioning expansion valve can reduce the efficiency of the air conditioning and affect driving comfort. Typical symptoms of a malfunction include:

• No cooling – The air conditioning does not cool the air in the cabin, despite the compressor working properly.
• Evaporator Freezing – Excessive amount of refrigerant in the evaporator can cause it to freeze.
• Irregular operation of the air conditioning – The system is unstable, which affects the comfort of use.
• Increased fuel consumption – An inefficient valve can increase the load on the compressor, leading to increased fuel consumption.

When replacement is required, Global Parts has the right used car parts that will restore the full functionality of your air conditioning system.

How to choose the right expansion valves ?

When selecting expansion valves, there are several key aspects to consider:

• Matching to the vehicle model – Each air conditioning system has its own specific technical requirements. At Global Parts you will find expansion valves perfectly matched to BMW , Audi , Mercedes , Volkswagen , Mini and others .
• Technical condition – Used valves should be fully functional, free from mechanical damage and corrosion.
• System Type – Make sure the valve you select is compatible with your vehicle’s air conditioning system.

Why choose used expansion valves ?

Used car parts , such as used expansion valves , is an economical solution that allows you to save money while maintaining high quality. By choosing used air conditioning components , you gain:

• Lower costs – Used valves are much cheaper than new ones, but offer equally high quality.
• Ecology – Recycling parts supports environmental protection and reduces waste.
• Wide range of products – In our shop you will find used expansion valves for the most popular car brands.

How to take care of expansion valves ?

In order for expansion valves to function reliably for a long time, it is worth following a few rules:

• Regular inspection – Check the condition of the valve during air conditioning system inspections.
• Keep the system clean – Contaminants can interfere with valve operation and reduce air conditioning efficiency.
• Air conditioning servicing – Regular inspections and refrigerant refills support the proper operation of the system.
• Replace on time – Damaged valves should be replaced to avoid problems with air conditioning operation.

When you need a replacement, Global Parts has the right used car parts to ensure the durability and efficiency of your air conditioning system.
